What to do if my Schumacher PBI1812 Extender won't jump start my car?
- WWilliam HortonAug 9, 2025
If your Schumacher Extender isn't jump starting your car, several factors could be at play. First, ensure the clips are making a solid connection to both the battery and the frame; clean the connection points and rock the clips back and forth. Also, verify the booster battery is adequately charged by pressing the button on the front. If problems persist, the vehicle's battery may be defective and should be checked.
